Paul Allen, co-founder of Microsoft and owner of the NFL's Seattle Seahawks and the NBA's Portland Trail Blazers, has died from complications of non-Hodgkins lymphoma, his family announced. He was 65.
Allen had announced earlier this month that the disease, which he had been treated for in 2009, had returned.
Allen's sister, Jody Allen, wrote in a statement: "My brother was a remarkable individual on every level. While most knew Paul Allen as a technologist and philanthropist, for us he was a much loved brother and uncle, and an exceptional friend."
Allen, who co-founded Microsoft with his childhood friend Bill Gates, had owned the Seahawks since 1997 and the Blazers since 1988.
